Tardar Sauce – better known as Grumpy Cat, the sour-faced puss which rose to Internet stardom five years' ago – has won a $710,000 (€572,000) payout in a copyright case in California.

Grumpy Cat Limited sued the owners of US coffee company Grenade for breach of contract after the store used the cat's image on several of its products, despite only having an agreement to use the cat for its "Grumppuccino" iced drink.

The damages will be paid to Grumpy Cat's owner Tabatha Bundesen, who has already made a mint from her pet, which was born with dwarfism and an underbite. In 2014, it was reported she had made £64m (€73.5m) from an array of commercial deals and products, including bestselling books and a film.

Ms Bundesen later said the figure was "inaccurate" although she refused to disclose her pet's true income.

Grumpy Cat is one of a number of pets to have earned their owners a fortune. In the age of the Internet, it has become easier for pet owners to show-off their cute and quirky animals, with many going on to secure lucrative merchandise and sponsorship deals. Below, we look at some of the pets that made their owners rich.

Moose, known on screen as Eddie, was the Parson Russell Terrier in TV sitcom Frasier, which won the role after six months of training. His ability to fix Kelsey Grammer, who played the titular character, with a long, hard stare – which became a running joke on the programme – contributed to him being hired.

Moose reportedly earned $10,000 (€8,000) per episode of the show, which ran for 10 years, giving him a net worth of around $3.2m (2.3m). In 2006, he died at the age of ​16, leaving his fortune to his owner Mathilde Halberg, a Los Angeles dog trainer.
